ADJUSTABLE FOOT-REST.

SPECIFICATION forming part of Letters Patent No. 619,467, dated February 14, 1899. Application filed July'24, 1897. Serial No. 645,820. (No model.)

To @ZZ whom, t may concern.-

Be it known that I, PHILANDER N. Cook, a citizen of the United States of America, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Adjustable Foot-Rests for Piano-Stools, Chairs, or Carriages, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to adjustable footrests, and has for its object to provide a footrest to be attached to chairs, piano-stools, or carriages that may be used on a variety of forms of seats supported in various ways and at the same time permit the step of the footrest to be raised or lowered for convenient use or closed or folded under the seat when not in use.

My invention consists of the construction and combination of parts hereinafter described, and pointed out in the claims.

Referring to the drawings accompanying and forming a part of this specication and in which like letters of reference indicate similar parts in the several views, Figure 1 represents an elevation of a piano-stool having attached thereto my adjustable foot-rest folded as when not in use; Fig. 2, a side elevation of the same, showing my invention extended, as when in use; Fig. 3, a front view of thel same, certain obverse duplicate parts being shown as broken away. Fig. 4 is a front view of an office-stool, showing my invention attached thereto with step pendent, as when not in use. Figs. 5 to 1l, inclusive, are enlarged views, Fig. .5 being a detail view of the step pendent with a portion of its connecting-support; Fig. 6, a vertical transverse section of a part taken on the plane of line Y V, looking in the direction of arrow 3, Fig. 7, the latter being a vertical longitudinal section of a part taken on the plane of line W W, looking in direction of arrow 4E, Fig. 6. Fig. 8 is a cross-section of one support at line X X, looking in direction of arrow 2, Fig. 9, the latter representing a side view of a part of one support provided with a modified form of clutch-operating device. Figs. l0 and l1 are cross-sections at lines Z Z and Y Y of one of the supports, looking in direction of arrows l and 2, Fig. 9, respectively.

My foot-rest comprises mainly a frame or brackets G, secured to the bottom of a seat and having grooves a2, extending from the front to the rear of the seat, supporting-arms L P, having lugs ct to move in the grooves, and a step R, pivoted to the supporting-arms, so that the parts may be folded and held beneath the bottom of the seat.

To the under side of a seat or step S is secured the frame G, which is provided with two longitudinal grooves d2, one on each side. Adapted to move in the grooves a2 are lugs a', Figs. 6 and 7, integral with the curved and offset portion of the primary pendent support L. Near the curved parts dof supports L are offsets or stops b, Figs. 3, 6, and 7. The stops b extend sufliciently to properly engage, when desired,with the ledge forming the lower walls of grooves a2. The said curved ofset parts ct a. permit the supports L P and step R to lie beneath and parallel to the longitudinal grooves a2, as shown in Fig. 1. also serve as braces, considered in connection with the stops b, to prevent the said supports L P,with the step R,from swinging backward when in use, and the upwardly-curved forward ends a3 of -the grooves c2 permit, within certain limits, the adjustment of the angle of the supports L P with that of the seat S, as illustrated by comparing Fig. 2 with Fig. 7.

Referring now to Figs. 2, 3, and 9 and describing but one of either side of parts named,

the lower extremity of the supportL is formed with lugs c to embrace a portion of the secondary or lower support P, and the support P is formed with lugs h, that partially embrace the support L, thus telescopi'ng the said supports L P together in such a manner that they can be lengthened or shortened at will. In order to maintain the support P, with the oonnected step R,at the desired height,olutches or pawls p are provided, Fig. 7 showing an interior section thereof. The said pawls p rest on a spring or other elastic device r, Figs. 2 and 9. One end of the pawl p is pivoted direct to support P, as seen in Fig. 2, or by a link Z', as shown in Figs. 9, 10, and ll. The downward pull of the support Pwill thus be The lugs a IOO conveyed to the pivoted end of the said pawls p, while their opposite ends will tend to raise by the expansion of the springs r, whereby the said pawls 19 will become cramped on support L, preventing further downward movement until the said pawls p are released, which may be accomplished by devices that can be operated to compress the said springs r, which will release the clamping effect of the pawls p and permit the downward movement of the said pawls p and their connections.

To the lower ends of the supports P, in the slots f thereof, in a manner to work freely therein, is pivoted at gthe step R, the bosses of which carry studs t, Figs. 1, 2, and 3, the said Figs. 1, 2, and 3 representing one form of a device for releasing the pawls p. Figs. 6 and 9 show another form of this device. Figs. l, 2, and 3 show spiral springs s, connected by extensions thereof or by rods u to the free ends of the pawls p and to the step R by the studs t. The tension of the said springs s is such that but little strain is made tending to draw the free ends of the said pawls p toward the said studs t when the said step R is in position for` use; but when the free end of said step R is raised the studs t are depressed, straining and extending the spiral springs s, and this pull by the connections of the rods u to the free ends of the pawlsp tends to compress the springs r, which may be of any suitable form or material, thus releasing the clutching or clamping eect of the pawls p on the support L and permitting the said pawls p and supports P to slip downward to the desired point. Upward movement of the arms P and step R is always possible because of such upward movement being communicated to the pivoted ends of the pawls, thereby unclutchin g the pawls p from the supports L.

InA the modification shown in Figs. 9 and 10 it will be observed that straight springs s' are substituted for the springs u, (shown in Figs. 1, 2, and 3,) the said springs s' being firmly secured to the pawls p, one spring s to each pawl p. When the position of the step R is as shown in Fig. 9, the said springs s', near their lower extremities, rest but lightly upon the studs t', that are secured to or form a part of the bosses of the step R; but when the free end of the said step R is raised the said studs t will thereby describe corresponding arcs on their radial pivots g, thus flexing the said spring s in a direction to depress the free ends of the pawls p, compressing the springs r, and releasing the clamping effect of said pawls p on the support L, for the purpose hereinbefore described.

The slots f in the lower ends of the arms P allow the pivot g of the step R to assume a variety of positions, as desired. Vhen said step R is at the point and in the position shown in Fig. 9, the abutmentsj on the step R rest on the front edges of the arms P, thus gripping the said arms P between the slots f and the front edges thereof; but when the free edge of the step R is raised the rear part or pivotal edge of said step R may be permitted to drop so low in the slots f that the abutments j find no resting-place, when the said step R can be made to assume the position shown in Fig. 5.

When my adjustable foot-rest is attached to a seat S having but one central support t, (see Figs. 1, 2, and 3,) the length of the step R from front to rear would not permit of its being pushed completely in unless cut away at o, as shown in Figs. 3 and 4, the front or free edge of the said step R in use being the rear edge when folded, as shown in Fig. 1. When, however, the seat S is supported upon legs, as shown in Fig. 4, and the distance between the said legs is less than the width from side to side of the said step R, the latter may depend from the arm P, as shown in Figs. 4 and 5.

Depending from the frame G are hooks m, which serve to hold the foot-rest in compact position when closed or folded, as shown in Fig. 1.

In order that the userof my adjustable footrest may be enabled to use the pedals of a piano or organ from the step R, I have provided supplementary pedals q, Figs. 2 and 3, said supplementary pedals q being held in proper position by means of the downwardlyprojecting parts q2 cl3 on the supplementary pedals that enter holes n in the step. To the forward ends of said supplementary pedals q are pivoted eXtensible rods k, terminating at their lower extremities with suitable claws that grapple with and rest on the pedals n of a piano or organ.

The rods 71:70 are each provided with screwthreaded bolts n2, that pass through longitudinal slots in the rods, and the parts are held in their adjusted positions by the thumbnuts n3.'

I claim- 1. The combination with a seat S, of brackets or frame Gr having grooves a2 a2 arranged opposite and beneath and in a plane parallel or nearly so with the plane of the seat, the said grooves having the forward upwardly-bent extensions or ends a3, the step R, and the supporting-arms therefor having bent ends a, lugs a to move in the grooves and enter the extensions a3, and stops b, at or near the ends a to bear against brackets Gr to hold the supporting-arms in a vertical position, substantially as shown and described.

2. In a foot-rest, the combination of the supporting-rods L P movable longitudinally upon each other, the pawl p pivoted to rod P and adapted to bear against the rod L,springr adapted to normally hold the pawl against rod L, step R pivoted to rod P, and means connecting the step and pawl for releasing the pawl by movement of the former, substantially as shown and described.

3. In a foot-rest, the combination of the supporting-rods L P movable longitudinally IOO upon each other, the pawl p pivoted to rod P and adapted to bear against the rod L,springfr to normally hold the pawl against rod L, step R pivoted to rod P, and a yielding connection between the step and pawl for releasing the pawl by the movement of the step, substantially as shown and described.

4. The combination with a seat S, of brackets or frame G having grooves a2 a2 arranged beneath and opposite and in a plane parallel or nearly so with the plane of the seat, supporting arms or rods having lugs a ct at their upper ends to move in said grooves and curved or bent at their lower ends and having curved slots ff, step R pivote-d in slots f f and adj ustable therein, and abutments j j on the step adapted to bear against the said bent end of the supporting-arms, substantially as shown and described.

5. The combination with the step R of a foot-rest, of the supplementary pedals q adapted to be supported and operated upon the step, and means for connecting the said supplementary pedals with the pedals of an organ or other instrument, substantially as described.

6. The combination with the step R of a foot-rest, of the supplementary pedals q adapted to be supported and operated upon' the step, and adjustable means for connecting the said supplementary pedals with the pedals of an organ or other instrument, substantially as described.

7. The combination with the step R of a footrest, of the supplementary pedals q adapted to be supported and operated upon the step, and the adjustable rods k cfor connecting the supplementary pedals with the pedals of an organ or other instrument, substantially as shown and described. g
